4. With the coolant surge tank
pressure cap off, start the
engine and let it run until the
upper radiator hose can be felt
getting hot. Any time during this
procedure, watch out for the
engine cooling fan.
By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
mixture to the coolant surge
tank until the level stabilizes at
the FULL COLD mark on the
coolant surge tank.
5. Replace the pressure cap.
Be sure the pressure cap is
hand-tight and fully seated.
Check the level in the surge tank
when the system has cooled
down. If the coolant is not at
the proper level, repeat Steps 1
through 4, then reinstall the
pressure cap. If the coolant is
not at the proper level when the
system cools down again, see
the dealer.
Notice: If the pressure cap is not
tightly installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
Engine Overheating
The vehicle has several indicators
to warn of engine overheating.
There is an engine coolant
temperature gauge on the
instrument panel cluster.
See Engine Coolant Temperature
Gauge on page 5‑16. The vehicle
may also display a COOLANT
OVER TEMPERATURE
message on the Driver Information
Center (DIC). See Engine Cooling
System Messages on page 5‑39
